Mariano Rivera threw 25 pitches -- sure, it was in a commercial, but those 25 pitches were still his first off a mound since undergoing ACL surgery in June.
The game's all-time saves leader turns 43 later this month and is technically a free agent, although it'd be a shock to see him sign with any team other than the Yankees.
"I'm feeling good," Rivera told reporters, including MLB.com's Bryan Hoch. "The rehab has been great. It's been tough, but at the same time, I'm seeing good results. I can't wait to continue and stay 100 percent. A day at a time, like I always tell you guys. A day at a time."
Rivera also said he wasn't rushing himself back in rehab, since he has until spring training to be ready.
Last week, he told Yankees general manager Brian Cashman that he wanted to pitch again in 2013.
"Like I told you guys before, I didn't want to go out like that," Rivera said, according to MLB.com. "At the same time, we haven't discussed anything. We're talking, so hopefully we'll finalize everything."
